We need below equipment for testing a CCTV camera.
Light Box, Gamma Chart, Resolution Chart, Color Bar, Vector Scope, Waveform and OSC Scope(>800TVlines)
First of all, what the specification we need to test a CCTV camera? Usually it is camera resolution, color, gray scale performance.
For a neccessery, we need a test chart. As below:
1 After placing the test chart, take the camera facing to the test centers, adjusting the distance of the camera and the test chart until the picture displayed take up the full screen, it is so-called, " test chart four angle into the chart ", remember to start it if the monitor has the “Under-scan function”, At this step you need to ensure your camera power is connected, and connect to the monitor. Ensure the monitor power light is on!
2 if possible, placed a lamp to each side of the testing chart, from a 45 degree angle to the chart, make the chart surface with a uniform illumination light, this will make you test easier.
3 Turn off the camera backlight compensation ( BLC ),and automatic gain (AGC ), white balance in ATW, if have not the switch, then ignored, continue the testing: cut to AES or CCD-IRIS ( manual lens is installed with the first gear), the lens aperture to the max, adjust the focal length, make the image to the clearest, then you can test chart for having an intermediate ring radially, marked Focus Target that codes for focusing.
Remember, please ensure test chart is filled full the screen.( four angle into the chart ).
